Musical intervention on anxiety and vital parameters of chronic renal patients: a randomized clinical trial

OBJECTIVE to evaluate the therapeutic effect of music on anxiety and vital parameters in patients with chronic kidney disease when compared to patients receiving conventional care in hemodialysis clinics. METHOD randomized clinical trial conducted in three renal replacement therapy clinics. Sixty people with chronic kidney disease undergoing hemodialysis were randomly allocated to an experimental group and a control group, 30 persons per group). State anxiety was evaluated in both groups by the State-Trait Anxiety Inventory. A t-test was used to verify the effect of the experimental manipulation on the variables. RESULTS we found a statistically significant difference between the groups regarding the degree of anxiety experienced during hemodialysis sessions. The experimental group presented a statistically significant reduction of anxiety scores (p = 0.03), systolic blood pressure (p < 0.002), diastolic blood pressure (p < 0.002), heart rate (p < 0.01) and respiratory rate (p < 0.006) after listening to music. CONCLUSION music represents a potential resource for nursing intervention to reduce state anxiety during hemodialysis sessions. Brazilian Registry of Clinical Trials: RBR-64b7x7.
